continue from the previous parallel reduction blog The result is obvious wrong, but what is the problem? The keen reader might point out that the program as written contains a race condition. Multiple threads can write into shared variable "sum" concurrently,...

A reduction is the process of combining elements of a vector (or array) to yield a single aggregate element. It is commonly used in scientific computations. For instance the inner product of two ndimensional vectors x, y is given by: This computation requires...

continue from the second parallel reduction blog . To get better scalability (increased program performance as the number of threads increases), it is critical to remove the lock in the upc_forall loop. This can be done by accumulating the partial sum...

Reducing the SNA test frame on the reliable network.
You can reduce the SNA test frame on your network, and the mainframe CPU (if the node is connected to mainfram) cycle, if your network is reliable. In general (by default), every 10seconds (Inactivity timer), the Communications Server for Windows sends test...

Analytical storage planning reduces procurement costs
A very useful method is the analytical storage planning based on measurement data. In the following example, the MS Exchangearea of a company was analyzed to determine the required supply power.

So much has been happening in OpenMP since SC 12 that I hope to capture it all in this post while flying to the ADC C++ meeting where I will talk about C++14, ISOCPP.org, and Transactional Memory.
First, the research arm of OpenMP is IWOMP, the...
